IPC: D04B27/00
Filed: 1967-10-18
Abstract: 1,245,246. Knitting-machines. GAINSBOROUGH CORNARD Ltd. 3 Sept., 1968 [18 Oct., 1967], No. 47405/67. Heading D1C. A device for measuring the rate of yarn feed in a warp machine comprises a pulse generator driven at the yarn feed speed and actuating a counter over a predetermined number of machine cycles. Rollers 38 bearing on the warps of a warp beam 10 rotate a cam wheel 40 which actuates a switch S6. Switches S6-S8, actuated by different beams, are connected by a selector switch S5 to operate a counter 41. A projection on the hub of sprocket 18 fixed to pattern wheel shaft 14, and a movable switch-operating cam 27 on a chain driven by the sprocket are arranged to co-incide after a predetermined number of machine cycles - say half a rack and close switch S2. Initial closure of switch S2 starts a count, while closure of S1 sets up a circuit of relay R3 for its actuation when S2 is next closed. When S2 is again closed after the predetermined number of cycles, the count is terminated and relay R3 actuated to ensure that a new count cannot be undertaken even though S2 may be closed. A re-set button restores the original circuit condition and zeros the counter. A counter reading at variance with the expected value permits the beam drive 12 to be adjusted manually or automatically. Switches S6-S8 can be de-activated by a cam working on the switch spring. Several separate counters might be provided in the machine; or the counter and relays can be arranged as a portable unit to be plugged into the machine. Several different sets of chains 23 and sprockets 18 may be provided so that the count period can be varied.

Abstract: 1,114,458. Welding by pressure. CATERPILLAR TRACTOR CO. 25 Nov., 1965 [3 Dec., 1964], No. 47418/65. Heading B3R. In bonding metal parts which comprise material which can precipitate a hard, brittle intermetallic compound, e.g. a carbide, ends of the parts are engaged in rotational rubbing contact under pressure, the initial speedof relative rotation and the total energy employed are restricted to minimize precipitation of substantial amounts of the compound and the bond zone is worked plastically at low speeds as the bond forms to shatter and disperse compound which does precipitate. A nickel base superalloy turbine wheel 12, Fig. 1, and a carbon steel shaft 13, the alloy and carbon steel containing sufficient carbon and carbide forming elements to precipitate carbides are friction welded at initial outer edge speeds of 400 and 265 feet per minute using a flywheel means to store the required energy and expend it all in making the weld, a small amount of carbide being formed at 400 ft. per minute and eliminated at 265 ft. per minute. The lower speeds require a greater flywheel mass which makes a large part of the stored energy available for low speed plastic working of the bond zone as the bond forms. The inside diameter of the lower strength shaft is less than that of the turbine wheel and the outside diameter is greater to produce a larger end face on the lower strength part to prevent excessive flashing away thereof. The nickel base super alloy and carbon steel may be welded using initial outer edge speeds of 150-400 ft. per minute and a cobalt base " Stellite " alloy (Stellite is a Registered Trade Mark) and carbon steel may be welded using initial outer edge speeds of 150-350 ft. per minute.

[Also in Divisions G1 and H2] In a machine tool, such as a milling machine, boring machine or a lathe, having a rotating part and a reciprocating part, the drive to the reciprocating part is automatically discontinued if an attempt is made to apply high power to the rotating part at a rotational speed so low as to produce a torque beyond the safe capacity of the gearing. As shown in Fig. 1, the current supplied to a drive motor 3 for driving a rotating part 1 passes through a coil 9 of a relay 8 and current from a generator 4 is fed to an opposing coil 10. When the speed of the rotating part is low and the torque generated by the motor 3 is too high, the current in coil 9 preponderates to switch the relay 8. Then, after a delay, the current is cut off from the motor 7 and a warning light or hooter may be energized. Delay means 13 prevents false operation due to transient loading. If the reciprocating part is driven by pick-off gears from the drive to the rotating part, the action of the relay would be to discontinue the pick-off by operating a clutch or sliding gears.
